At some point though you shouldn't want to lose anymore weight. Unless you start out really overweight, simply losing weight shouldn't be the goal anyways. Lowering BF% is a much better goal that reflects your overall body composition. I'm 6' 1" and almost 200lbs and weight wise I could be considered overweight, but my BF% was 11% the last time I had it checked and I've since gotten leaner.

In short, don't get depressed about the scale. Look in the mirror and keep making body composition changes.
